The reliable injection of air through a ventilation duct of high quality is without a doubt the best investment that can be made in an underground project. Both workers and machines will be more productive when the air supply has the best possible conditions. Many examples exist of projects on which savings of 2-3% have been made in purchasing prices for the ventilation system, but which have subsequently endured many production stoppages because damages had cauused such large leaks that nearly no air was being transported to the workplace.
Selection of Supplier
Every stoppage costs many times more than the normal price differential between a good and less good ventilation duct. The best guarantee is to purchase the ventilation duct from a serious supplier, a supplier with longstanding experience and with continuous and professional production. A good piece of advice would be to require ISO 9001 certification. It is also good to require ISO 14001, which shows that the supplier is not just producing the product, but is also interested in it being produced and used in an environmentally appropriate manner. A supplier who has these quality certifications has a good knowledge of how the product is used and can make a great deal of expertise as well as a high level of service avaliable for both installation and operation.
